Hi Peter,
Gaket material are covered as Recognized Plastics material. They are in the
yellow books, just like regular plastics material (QMFZ2). Some gasket
material were Recognized under that QMFZ2 category, but there is also a special
category (Q) that covers gaskets in particular. I
). Where you use
it and how you use determines what UL marks concern your inspector and
installer.
I hope this helps!

those criterion from similar product standards to your product can
indirectly cover expectations of your customer.
As for criterion B, I would say no, shut down for ten minutes and then
recoverable is criterion C.
Hope this helps.

, this is a good option for non-halogen
applications, just more expensive with less applications than PVC.
Good Luck. If you need any more info, you can contact me directly.

. The other numbers you
mentioned are probably UL Style numbers, referencing various wire and cable
construction Recognized by UL with restrictive conditions of acceptability. I
recognize those numbers as some popular internal wiring Style numbers.
I hope this helps.

Hello All,
I have to agree that there shouldn't be another US (UL) standard for network
equipment when the equipment can be incorporated into UL1950. UL1950 can be
revised
to clarify the network equipment requirements, perhaps as a deviation or an
appendix (annex), or just rewording the existing
Hello Moshe,
UL1581 is the UL standard that covers test methods for many of the most common
wire and cable
tests performed on a variety of Listed and Recognized wire and cable types.
The standard includes test methods for many tests, including: Physical
Properties tests on
various insulation and
Hi all,
I have a question to clarify..
Is it to be understood that the EC DofC can be signed by the US manufacturer,
and authorized copy of said document just has to reside with the rep in the EC?
This could save me a lot of time and bs.

Ray,
I agree with your interpretation. Besides your good reasons, testing each port
individually assures as much repeatability and uniformity of application of the
transient field as possible...

Robin,
You do not scale the thickness as such when increasing the voltage rating.
Insulation Thickness is directly related to the degree of Mechanical
protection that needs to be achieved. Insulation thickness is only
partially (brain stoppage for lack of a better word!) related to
voltage
Hi Doug,
Sounds, most likely like the old telephone game, ie, he heard that she said
that he said that this is what we had to do.
I've never heard of such a thing as you stated it. Most likely, the Dell group
had to replace wire that was somehow unsuitable for whatever application they
were
Lisa,
The 10 ohms per square seems high to be critically connected with EMC
directly..(maybe ESD ONLY???). I would have to say that the move to 20 ohms
won't have much of an effect
Now, the retest debate is interesting... If you have a TCF, I would
recommend submitting your changes to
Doug,
You may already know the standards that cover the CTI test, but I thought I'd
list them anyways: ASTM D3638, IEC 112, and UL746A
Those sources will give you the test methods to help interpret any results,
and also to compare IEC ratings with UL ratings.
I believe that is what you

Rick,
The Comparitive Tracking Index (CTI), ASTM D3638 and UL746A, is a test intended
to show the susceptibility to surface tracking of solid electrical insulating
materials when exposed under electrical stress, to a contaminant solution.This
test applies to relatively low voltages under 600
Bob,
Thanks for the clarification.
I got those notified and competent bodies confused, apparently.

Mel,
What you state I agree with you in Ed's case, but there are circumstances
where he may want to set up a TCF with a notified bodyOne of the cases
being if his unit is too large to test normally, and would need a field
evaluation... In that case he would want a notified body report to
Hi Everyone,
I have an update on that 500-900 mv spike at 50MHz that we encountered on
our power lead. Attempts to alleviate the problem outside the power supply,
by the use of torroids and adding ground connections did not help as much
as needed, so we immediately turned our attention to the
